摘要
转基因技术是研究植物发育的有效的途径。比利时的作物设计公司(CropDesign)成功研制出称为TraitMill的技术平台,TraitMill平台不仅是一个能够大规模开展转基因和植株评价的高通量的技术平台,而且还是一个在植物表型上鉴定基因和基因组合的非常有用的工具。无论是在理想的植株生长条件下,还是在不同非生物逆境或营养胁迫条件下,利用TraitMill平台每年可成功地鉴定成百个不同的“启动子—基因”组合。基于对水稻生长发育的特别设计和高精度的测量方法改造,TraitMill平台已经全面应用于水稻转基因及其性状的评价。迄今为止,TraitMill平台是唯一一个将转基因技术和植株性状自动化评价系统相结合的技术平台。显然,应用于改良禾谷类作物产量基因的鉴定,TraitMill平台具有独特的优势。
Transgenesis is a powerful and effective mode to study plant development. CropDesign has developed the TraitMill platform, a high-throughput technology that enables large-scale transgenesis and plant evaluation. The TraitMill is a highly versatile tool for testing the effect of genes and gene combinations on plant phenotypes. It can be used to successfully evaluate hundreds of independent promoter-gene combinations per year, either under optimal growth conditions or under different abiotic or nutrient stress regimes. The TraitMill platform operates in rice and is specially designed to measure alterations in growth with high sensitivity. To date TraitMill is the only platform that combines these two features and is therefore uniquely placed to identify genes that imorove the yield of cereals.
